Not too familiar with these, to me it looks like an unplated planchet. It's not pitted as it was given an acid bath.   |

Looks more like environmental damage. John1  |

What would do that? There's not a speck of copper on this thing.

Give me an accurate weight in the hundredths, (0.01 etc.)...it does look promising to be a true unplated blank/planchet, BUT the detail is too sharp, it could be an electroplated stripped coin (see all the DIY YouTube Vids). If it is 2.25-2.35gr, that just indicates plating loss. If 2.4-2.6, is just discolored.

Crazyb0, thanks for the weight indicator. I will weigh and post by 5pm.
Funny enough, I found a 1994 a while back that wasn't as sharp as this one and figured that someone may have altered it,
but now from what you're saying I might give that one a second look also.
The info on the web is sort of all over the place with these so it seems hard to tell.

I thinking that it's an altered coin. Maybe someone removed the plating on your coin.
Errers and Varietys.

Perhaps. That's what I'm trying to determine.

This is a normal coin that someone added a zinc coating. See the zinc dust that was plated over? Add the weight of the zinc. Then you've figured out what happened to your coin.

Hi Coop, thanks for weighing in.
I'm starting to see how counterfeited these are after posting this here. I gotta say though, if this is altered I'm surprised w the amount of detail still left on the coin.
If it is a zinc coating then what you're saying is they removed the copper, then added the zinc?

If someone added zinc,why doesn't it weight more? John1 |

Environmental in my opinion. See them a lot like that here in Florida after sitting a hot car or something in the humidity for a couple years of. If it wasnt stained then maybe, but it looks like maybe it had something spilled on it, dried out and turned into this. Like I said though, just my opinion.

I never thought the environment could strip the plating off a coin like this. Maybe so.
I think I'm going to take this one to a shop and see what they say. I know a lot of people make these but I would love to have a genuine one for the collection.
Thanks for the feedback folks.

The surface on them would be smooth.  There are youtube videos on how this is done. But what stood out at me was the copper plating over the dust leaving raised marks. You can see the on the coin and more roughness from the adding of zinc on the surface.  |

So with a spec weight of 2.5 grams with a tolerance of .1 grams a regular cent could weigh from 2.4 to 2.6 grams. So if the black missed the plating process that would give it a possible weight range of 2.34 grams to 2.54 grams and almost complete overlap of weight ranges. Weight really isn't going to tell you anything. Quote:
If someone added zinc,why doesn't it weight more? Maybe it does. You don't know what it weighed before the zinc was added. If it weighed 2.43 grams before they zinc plated it (which is within the spec tolerance range) and they added as thick a layer of zinc as the thickness of the copper plating,(about .06 grams worth) it would end up actually weighing slightly less than that 2.49 grams mentioned. The only real way to authenticate non-plated cents (as opposed to unplated which implies that a plating was removed) is for the coin to be AU or MS, and it must have SMOOTH surfaces and show cartwheel luster. A zinc plated coin won't show luster because the microscopic flowlines have been "filled". And it may show plating blisted in the underlying copper plating. A circulated, corroded or oxidized non-plated zinc cent can show the same dark rough and/or pitted surfaces that a cent with removed plating will show. So if it isn't smooth and showing cartwheel, it's not going to be accepted as a non-plated zinc cent. |
